Although prostatic calculi are relatively common, the etiology of these stones is not clear. We report a case with multiple prostatic calculi causing urinary obstruction and a concomitant bladder stone. We treated these stones endoscopically. We found a lot of different sized stones endoscopically, some protruding into the urethra, some filling different cavities on the prostate. So these cavities suggest prostatic calculi may occur related to intraprostatic reflux in the congenital or acquired diverticulum of the prostatic tissue. In addition, the stone composition of the bladder and prostatic stones was the same. All of these results show that the origin of bladder and prostatic stones can be the same. This case also supports a theory of intraprostatic reflux and urine stasis. 相似文献

PURPOSE: The aim of the present study was to evaluate whether relief of partial unilateral ureteral obstruction (PUUO) with or without antioxidant drug affect renal tissue malonedialdehyde (MDA) and glutathion (GSH) levels. MATERIALS AND METHODS: A total of 25 rats were used in this PUUO study. Partial unilateral ureteral obstruction was created by the burial of the upper one-third of the left ureter in the psoas muscle. The rats were sacrificed on 28th day following PUUO. Relief of the obstruction was performed twenty minutes before sacrifice by cutting the proximal ureter in reperfusion group. 50 mg/kg intraperitoneal allopurinol was administered 20 minutes before relief of obstruction in the antioxidant group. Renal tissue MDA and GSH levels were measured in both kidneys. RESULTS: At the end of the study 5, 7 and 7 rats could only be interpreted in sham, reperfusion and antioxidant groups, respectively. While the mean left and right renal MDA and GSH levels were statistically different from each other in reperfusion group (P < 0.001), there were no significant differences in the sham (P > 0.05) and antioxidant (P > 0.05) group. Both the mean sham group left and right renal tissue MDA or GSH levels were significantly different from reperfusion group, but only the mean sham group left renal tissue MDA and right renal tissue GSH levels were not statistically different from antioxidant group (P < 0.05). The mean left or right renal MDA and GSH tissue levels of the antioxidant group were statistically different from reperfusion group (P < 0.05) except for the right renal tissue GSH level (P > 0.05). CONCLUSION: Partial unilateral ureteral obstruction leads to oxidative injury by relief of obstruction in both kidneys. The antioxidant allopurinol has a beneficial effect on renal MDA and GSH levels in both kidneys. 相似文献

Thromboangiitis obliterans (TAO) or Buerger's disease is a clinical syndrome characterized by the development of segmental thrombotic occlusions of the medium and small arteries of the extremities. Exception of the peripheral arteries of the extremities in TAO is very rare. Reported herein is the first case of intrarenal branch involvement of the renal artery due to TAO. 相似文献
